1 time Error. Ambulance crew left at station.

An ambulance was dispatched and had 2 crew assigned to it. Upon arrival at the scene it didn't provide patient care, so upon investigation it said it had 0 crew. I then looked at the crew at station, and it said the crew was available and not on a call, even though their assigned Ambulance was out at a call. I canceled the Ambulance with no crew and dispatched another one and it worked fine. This is a strange issue because it is a 1 time thing, on 1 Ambulance.
The issue was only earlier tonight( 4/16/2017 @ 2129 -0400 UTC )

Again, this is a strange issue, and don't really think there is a way to fix the problem, because there probably no way to diagnose the problem. Best of Luck.

Me as well, I've just ignored it as it eventually resolves itself. Juggeroni, one way to solve this could be by binding personnel to that unit.

I stated that I had 2 crew assigned to the vehicle. Or 2 personnel binded to the unit.

Try making the unit state 6 and then making it available again, if that doesn't work try deleting the unit and re purchasing it

I let the unit return and it returned back to normal, as stated just a weird one time bug.
